Hams, Broadcast Engineers, and Cancer-Causing Smart Meters

Full disclosure: I am not an epidemiologist. Other than a gut feel, I have no idea how valid my sample sets are. (Not true: my samples are totally invalid; they are strongly biased toward people, mostly males, who spend or spent most of their adult lives in strong RF fields, and there is no control group. I still think my conclusions are interesting.)

This rant is about a news release that came in my email this morning. It's from the Electric Power Research Institute (EPRI, www.epri.com), and it's about RF field measurements on "smart" power meters for residential electricity customers. The release is about a report that says the fields EPRI measured are way below what the FCC allows.

EPRI gets support from the electric utilities, and they work closely with them, but I trust them not to lie about test data.

The key point about the meters is where they operate in the RF spectrum. The report (An Investigation of Radiofrequency Fields Associated with the Itron Smart Meter 1021126) states: "Mesh network communication among the many meters is provided by a 900 MHz band transceiver RF LAN (local area network). A HAN feature is supported by a 2.4 GHz transceiver."

Checking EPRI's site for more information led me to a short piece about the smart grid in muck-raking Mother Jones, which has never been shy about speaking truth to power (or Power). You can read the article at: http://motherjones.com/blue-marble/2011/01/will-smart-meters-give-you-cancer. The answer to the cancer question is, "No." and the rest of the article is a nice clear explanation of the parts of the smart grid that rate-payers might want to know.

What I think prompted the EPRI study is the aura of paranoia that I perceive to surround green energy today. It reminds me of Aunt Clara, who used to put Scotch Tape over unused electrical outlets.

As an example, one source that I find on the Web is the SIG site for Prius owners (http://priuschat.com) that I monitor. (I have a 2010; I don't hypermile; I get about 47 MPG on winter-blend fuel, 50 on summer-blend.)

An unexpected large number of posters on the SIG seem to have a fixation on having their brains fried or turned into alien growths by EMF inside the car. And that's what brings me to the topic of epidemiology.

    Don, late comment but I just found this. Also a ham since 1954. Somewhat more concerned about low frequency (60Hz) magnetic fields since experiencing a problem (now cured) with a one of our daughters who spent several years pre teen sleeping with her head in a 20mg field from an utility meter on the other side of her bedroom wall .. later discovered when I got interested in bio effects of EMFs.
    When you consider that 100mW ERP of HF RF is enough to propagate half way around world and be 12db or more above some receiver noise floor, physiological interaction of some sort is not out of the question but experiments are very difficult to devise and repeat; low fields may have more effect than high and developmental years may be most sensitive.
    Had a retinal melanoma in 1997 successfully treated with proton beam therapy; cause of retinal melanomas is not understood, but more frequent in males and they don't seem as related to dermal melanomas as once thought. I breathed my share of soldering fumes as well as carbon tet and oil cap PCBs as a kid as well. I more or less go along with David Carpenter's (NY School of Public Health) idea of 'prudent avoidance'.

    we now usually use PCB/FPC antenna for tablet pc / UMPCs

    Terry, I think Don comments about the bus were subliminal. My mother, Don's mother-in-law was indeed run over by a bus. A Metro bus in downtown Seattle. She survived and even got a settlement from Metro. She passed away a few years ago from a brain tumor. She was not a cell phone user. (or a ham)
    She lived near Sea Tac airport. If it was environmental causes, I have no idea what. Jet fuel fumes? Radar? Aspartame?

    Our daughter attends the UW and takes Metro almost every day to school. Anyway to make One-Bus-Away even better?

    The US government has taken the position that heating tissue is the only criteria for assessing RF/EMF effects on humans. Think about it for a moment; do you worry about getting cancer from a campfire?
    The real problems occur with biological resonances. Tiny little LC tank circuits that can be overstimulated by picowatts of power. Depending where the resonance occurs, effects may not be noticable, or could interfere with endocrine and regulatory systems. If it persists over a long period of time, disease results.
    How many of us "extraordinarily tough old buzzards" have high blood pressure, heart disease, arthritis, prostate problems, and on down the list, and think its just a part of getting old? Most of these diseases have increased along with increased RF exposure of the population. Causal, maybe not, but can you prove it? It doesn't have to kill you to be a problem.

    Sorry for the multiple posts - I kept getting errors which apparently did not stop the posting...

    Perhaps the moderator can remove them - I don't seem to be able to.

    Besides this anecdotal information, very significant numbers of medical studies have been undertaken to determine the effects of RF radiation on the human body. Microwave radiation is readily absorbed by the human body and results in warming of the flesh. Enough power can raise the temperature quickly, but no risk of cancer has ever been detected. UHF (cellular) and VHF (FM/TV) radiation is less readily absorbed, and HF/MF/LF (AM broadcasts) progressively less so. Yet at all of these frequencies the effect on the human body of even high power RF is similar to raising the room temperature a degree or two -- there's no trace of cancer risk.

    That compares with the measurable cancer risk associated with even living within sight of a small city due to pollutants.

    This is an interesting scientific preliminary study:

    The author is careful not to draw a conclusion other than there is a good case for a more formal and controlled study.
